Access to maintenance working documents in a mill environment. A case history

Accessibility to working drawings and other information for maintenance work forces in a mill environment has always been a concern and continues to be a concern, especially for some older mills. This paper is a case study of the development of a method to provide electrical and other documents to the maintenance and engineering work forces at the West Tacoma Mill. The intent is to show the steps taken over time which, although still evolving, are resulting in complete electronic availability of electrical and instrumentation and other engineering documentation. Development of a maintenance document system for the electrical and instrument group at this mill was the result of a long strategy of improvement, much like the pieces of a puzzle that finally comes together. Following steady evolution towards modern control systems has allowed the mill to develop a totally integrated control and information system.
